There’s a story in the news right now about someone crashing into seven parked cars at the Dallas Stars parking lot but the part I’m interested in is how this somehow ripped a cybertruck in half?? Like clean in half??

yes, I believe it is the mechanism behind cold working and peening, but I don’t think it changes the grain structure. Definitely a complex field that I am only barely familiar with.
I’m sure it behaves differently in aluminium vs steel, too.
